Title: Production of coat protein of hepatitis c virus
Inventor: MIYAMURA TATSUO
IPC: C12R1/91
Filed: 1992-06-11
Abstract: PURPOSE:To efficiently obtain the subject substance useful as a hepatitis C vaccine, for diagnosis, etc., by transforming a host with an expression vector containing a DNA fragment capable of coding a coat protein of hepatitis C virus, culturing the resultant transformant and then collecting the extracellularly produced substance. CONSTITUTION:A 50mM tris buffer solution is added to a blood serum of a patient suffering from hepatitis C and the resultant mixture is centrifuged at 20 deg.C for 20min. The obtained supernatant is ultracentrifuged for 5hr and Protenase K(R) and sodium dodecyl sulfate are then added to the formed precipitate to carry out the lysis. The lysate is subsequently extracted with phenol/chloroform to recover nucleic acid, which is then used to synthesize a cDNA. The synthesized cDNA is treated with a restriction enzyme and bound to a vector. The resultant DNA is used to transform Escherichia coli. The transformed Escherichia coli is cloned to sort out a positive clone and its plasmid is recovered, treated with a restriction enzyme and bound to an expression vector. A host is transformed with the resultant expression vector containing a DNA fragment capable of coding a coat protein of the hepatitis C virus and cultured to obtain an extracellularly produced substance. Thereby, the objective coat protein of the hepatitis virus C is provided.

Title: Communication channel selecting system
Inventor: MATSUSHITA HISAHIRO
IPC: H04B7/26
Filed: 1989-06-16
Abstract: PURPOSE:To prevent the lowering in the communication efficiency by retrieving an idle channel with a slave station, informing the result to a master station and allowing the master station to select a succeeding communication channel based on the idle channel information from the slave station. CONSTITUTION:Slave stations 1-N send the data to the master station sequentially in time division with a polling signal from the master station and other stations except the slave station N uses the idle time to retrieve the data. When idle channel information is received from each slave station, the master station stores it in its memory, retrieves an idle channel whose preceding and succeeding channels are idle based on the idle channel information, decides the idle channel to be the succeeding communication channel and sends a channel switching command to the slave stations 1-N. When an idle channel whose preceding and succeeding channels are idle does not exist, and an idle channel whose preceding or succeeding channel is idle is retrieved to decide it to be the succeeding communication channel. Thus, without the need of interruption of the communication with a slave station by the master station, the lowering in the communication efficiency is prevented.

Title: Reducing method for sliding resistance of switching apparatus sliding component
Inventor: SHINOHARA HISAJI
IPC: C10N40/02
Filed: 1994-07-06
Abstract: PURPOSE:To enable sliding components to be always smoothly taken in and out by applying lubricant to their sliding surfaces to match reduction in the fluctuation range of the sliding resistance of each sliding surface, and using a fluoro-oil-containing lubricant. CONSTITUTION:Fluoro-oil is a synthetic oil containing fluorine as one of its constituent elements, the fluorine (its unit is a diatomic molecule F2) having the highest electronegativity (4.0) among all the elements. Because of its weak F-F bond and the strength of the bond of F to other elements, fluorine is most reactive among the units of all the elements, and reacts with all the elements except N2 at room or high temperature to produce a very stable organic compound. The fluoro-oil fabricated has high thermal stability, is not much decreased in viscosity in the temperature range that normally arises, and so maintains an oil film even under contact pressure. Also, the fluoro-oil has a permanent rustproofing effect on any sliding surface and prevents aged deterioration of contact resistance over a long period.
